Trial Summary

What is the purpose of this trial?

The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.

Do I need to stop my current medications to join the trial?

The trial requires a washout period (time without taking certain medications) for some treatments before starting the study. Specifically, you must stop taking strong CYP3A inhibitors and certain other medications for a specified time before enrollment. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

What data supports the effectiveness of the drug Ceralasertib + Trastuzumab Deruxtecan for solid tumors?

Trastuzumab deruxtecan has shown effectiveness in treating various HER2-positive cancers, such as breast and gastric cancer, with patients experiencing significant responses. It has been approved for use in HER2-positive breast cancer after other treatments have failed, indicating its potential effectiveness in similar conditions.12345

What is the safety profile of Trastuzumab Deruxtecan (Enhertu) in humans?

Trastuzumab Deruxtecan (Enhertu) has been shown to have a generally manageable safety profile in humans, with common side effects including blood and stomach-related issues. However, it carries warnings for lung disease and potential harm to unborn babies, so careful monitoring is needed.13467

What makes the drug Ceralasertib + Trastuzumab Deruxtecan unique for treating solid tumors?

This drug combination is unique because it includes Trastuzumab Deruxtecan, a novel antibody-drug conjugate that targets HER2 (a protein that can promote the growth of cancer cells) and delivers a potent chemotherapy directly to the cancer cells, potentially improving effectiveness while limiting damage to healthy cells.12346

Treatment Details

Interventions

  • Ceralasertib (Enzyme Inhibitor)
  • Trastuzumab Deruxtecan (Monoclonal Antibodies)
Trial OverviewThe DASH trial is testing the combination of two drugs: DS-8201a (trastuzumab deruxtecan) which targets HER2 cancer cells with attached chemo drug deruxtecan; and AZD6738 (ceralasertib), which may halt tumor growth by blocking certain enzymes. The study has two phases to determine safety and compare responses in colorectal/gastroesophageal cancers.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: Treatment (trastuzumab deruxtecan, ceralasertib)Experimental Treatment8 Interventions
Patients receive trastuzumab deruxtecan IV over 30-90 minutes on day 1 of each cycle and ceralasertib PO BID on days 1-7 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. NOTE: During the dose-expansion phase, the first 6 patients in each disease cohort (gastroesophageal cancer \[cohort A\] and colorectal cancer \[cohort B\]) receive only trastuzumab deruxtecan for the first cycle, followed by trastuzumab deruxtecan and ceralasertib together in subsequent cycles. Additionally, patients undergo tissue biopsy on study and blood sample collection, CT or PET/CT and ECHO or MUGA throughout the study.

Findings from Research

Trastuzumab deruxtecan (ENHERTU®) is an innovative treatment that combines an antibody targeting HER2 with a DNA topoisomerase I inhibitor, specifically designed for HER2-expressing solid tumors, including various types of cancer.
It received accelerated approval in the USA based on the promising results from the phase 2 DESTINY-Breast01 trial, which focused on patients with advanced HER2-positive breast cancer who had already undergone multiple treatments.
Trastuzumab Deruxtecan: First Approval.Keam, SJ.[2020]
In a phase 2 study involving 184 patients with HER2-positive metastatic breast cancer who had previously been treated with trastuzumab emtansine, trastuzumab deruxtecan demonstrated a significant response rate of 60.9%, with a median response duration of 14.8 months.
While trastuzumab deruxtecan showed promising efficacy, it was associated with notable adverse effects, including interstitial lung disease in 13.6% of patients, highlighting the need for careful monitoring of pulmonary symptoms during treatment.
Trastuzumab Deruxtecan in Previously Treated HER2-Positive Breast Cancer.Modi, S., Saura, C., Yamashita, T., et al.[2021]
In a phase 1 trial involving 44 patients with HER2-positive gastric or gastro-oesophageal junction cancer, trastuzumab deruxtecan demonstrated a manageable safety profile, with the most common serious side effects being anemia and decreases in blood cell counts, but no drug-related deaths were reported.
The treatment showed promising preliminary activity, with 43.2% of patients achieving a confirmed objective response, indicating its potential effectiveness in patients who had previously been treated with trastuzumab.
